TO ALL WIIOM I'l MAY CON CERN:

Be it known that I, D. A. DICKINSON, of the city of Baltimore, in the State of Maryland, have invented a certain new and useful Improvement in Ventilating and Drying Corn and other Grains in Cribs, 85o.; and I do p hereby declare that the following is a full, clear, and exact description of thexeonstruction and operation of the same, reference being had to theaceoinpanying drawings, and to the letters and marks thereon, which said drawings form part of this specification, and represent my invention applied to a. bin. Y

It is very important, when any kind of grain is stored, whether it be corn in the crib or any other grain in bulk, that it be so placed as` to have a free. circulation of air through it, either by the natural motion ot' the air or by a forced circulation, of either air at the natural temperature, orV heated up to whatever degree may bc regarded necessary under the conditions and circumstances existing.

I have endeavored, under my invention, to makefull provision for such needed circulation of air, as, also, for disturbingthe corn or grain in bulk, in order to have the whole fully exposed to the air, and for the passing out and delivery of the entire quantity of corn or grain by its own weight.

In the sides or ends of the crib or bin, a, holesl are bored, or otherwise made, for the admission of the air. Between `the Ksides or ends, and to the inner -surface of each side or end, inverted V-shaped covers, b, extend, which covers,in wooden structures, can be secured by screws or nails, and in brick or other structures by clamps and plates, or other suitable means and devices. These covers may be widened out to a greater extent than shown bythe drawings, and the sides of these should come down toda line even wtih or slightly below the lower part ofthe holes, which is lower than the drawings show. `.llnesecove'rs, will, in many instances, serve to strengthen a crib orstructure designed to held the grain. When they may bedeemedinsuioient, tie-rods may be passed immediately under the angle of' the cover, and secured to the sides or ends of the structure, thus making the covers alsoact as thrusts.

When heated `air is used for Ventilating or drying, one end of these covers may be higher than the other, to facilitate the circulation; and the bil-nsor cribs 'may' be s'o arranged in regardfto each other that a heatingchamber or the heating-pipe may be between. the ends, the heated air thus having room for frcc circulation i through all the bins or cribs.

This invention may be applied to the bins, cribs, storehouse, or cvcn to cars, when they are boing built, or afterwards, as the holes can readily be made through the siding or walls, and the covers iitted in. When usedl in cars, the 'motion of the car n'ill not force the grain under the covers and through the holes, as has been ascertained practically.J 5

To the end of the bin there is attached a closed chute, c, having sliding doors or' valves,` cZ and e. The

space between these doors may be made to answer as a measure for any certain number of bushels. The raising ofthe upper or inmost door will let tho grain run in-to the space, and then the shutting of it, and the opening oi' the lower door, will allow the grain' to run out. To this chute an indicator` can be attached, so that the quantity of grain thuspas'sed through can beregistered.

When the grain com es down into the chute, that in the bin will all be more or less disturbed, bringing the portion of the grain remote from the covers nearer to them, so that whenever it is desirable toaid the ventilatingor drying of the grain, a certain quantity carrbc taken from the bottom ofthe bin and put in at the top,

'and thusthe position of the grain changed.

`'The bottom of the binis inclined towards the chute, as is indicated by dotted lines through` the coloring of the drawing. I lWhile the covers will allow the grain to pass down, the inclination o t' the bottom will per-mit all the grain to pass out of thevhin through the chute, and thus a ear-load of grain could bc delivered measured.

As is evident, the covers may be made of wood or metal.

What I claiui as my invention, andvdcsire to secure by Letters Patent, is

Ventilating and drying corn `and grain byamcans of the inverted V-shaped covers and holes in the siding or walls, as herein recited. i
